Pay per stream is what the industry negotiated. To me subscriber share is dumb. If I listen to two songs in a month by two different artists and nothing else they get paid the same as if I streamed all their music non stop. The root problem is that too many people think music should be free or close to free. Young people don’t have music collections (if they do, it is usually 100% stolen) and rely completely on streaming services. The only way this can replace CD sales as a revenue stream is for subscription fees to be higher than the users are willing to pay. So the music industry is upside down. People used to tour to sell recordings. Now the recordings go out to draw people to their concerts. You can argue about the rate of pay, but pay per stream is hardly some sort of conspiracy to cheat anyone.
